The Meyer and Land Threshold Concept "The idea of threshold concepts emerged from a UK national research project into the possible characteristics of strong teaching and learning environments in the disciplines for undergraduate education (Enhancing Teaching−Learning Environments in Undergraduate Courses). In pursuing this research in the field of economics, it became clear to Erik Meyer and Ray Land [1−6, 7−12], that certain concepts were held by economists to be central to the mastery of their subject. These concepts, Meyer and Land argued, could be described as 'threshold' ones because they have certain features in common." Glynis Cousin, An introduction to threshold concepts Over the past five years this concept has been embraced by many disciplines outside economics; indeed the above quote is from Glynis Cousin's excellent short introduction to the concept written for earth scientists. The threshold concept has been seen as a valuable tool, not only in facilitating students' understanding of their subject, but in aiding the rational development of curricula in rapidly expanding arenas where there is a strong tendency to overload the curriculum (Cousin, [1, 13]). This web page will describe, briefly, the characteristics of a threshold concept and list selecteted references to the work of those examining its value in the engineering and computer sciences, the physical and biological sciences, economics, accountancy, mathematics and statistics.

Abstract A recent draft manuscript suggested that Facebook use might be related to lower academic achievement in college and graduate school (Karpinski, 2009). The report quickly became a media sensation and was picked up by hundreds of news outlets in a matter of days. However, the results were based on correlational data in a draft manuscript that had not been published, or even considered for publication. This paper attempts to replicate the results reported in the press release using three data sets: one with a large sample of undergraduate students from the University of Illinois at Chicago, another with a nationally representative cross sectional sample of American 14- to 22-year-olds, as well as a longitudinal panel of American youth aged 14-23. In none of the samples do we find a robust negative relationship between Facebook use and grades. Indeed, if anything, Facebook use is more common among individuals with higher grades. We also examined how changes in academic performance in the nationally representative sample related to Facebook use and found that Facebook users were no different from non-users.
